Equipment You’ll Need

• 12-inch large skillet (cast iron or non-stick recommended)
• Wooden spoon or spatula
• Chef’s knife
• Cutting board
• Measuring cups and spoons

Ingredients

• 1 lb ground beef (80/20 or 85/15 recommended)
• 1/2 large yellow onion, chopped
• 1 medium bell pepper (any color), chopped
• 2 cloves garlic, minced
• 1 tbsp chili powder
• 2 tsp ground cumin
• 1 tsp smoked paprika
• 1/2 tsp dried oregano
• 1/2 tsp salt (or to taste)
• 1/4 tsp black pepper
• 1 (10-ounce) can diced tomatoes with green chiles, undrained
• 1.5 cups shredded Mexican cheese blend (or cheddar/Monterey Jack)
• Optional toppings: sour cream, sliced avocado, fresh cilantro, jalapeño slices, lime wedges

Instructions

1. Heat a large 12-inch skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until browned, about 4-5 minutes. Drain off any excess grease.
2. Add the chopped onion and bell pepper to the skillet with the beef. Sauté for 3-4 minutes, until the vegetables begin to soften.
3. Stir in the minced garlic, chili powder, cumin, smoked paprika, oregano, salt, and pepper. Cook for another minute until the spices are fragrant.
4. Pour in the can of diced tomatoes with green chiles (undrained). Stir everything together and bring the mixture to a simmer.
5. Reduce the heat to low, ensuring the mixture is evenly spread across the pan. Sprinkle the shredded cheese evenly over the top.
6. Cover the skillet with a lid and let it cook for 2-3 minutes, or until the cheese is completely melted and bubbly.
7. Remove from heat. Garnish with your favorite toppings like a dollop of sour cream, fresh cilantro, and sliced avocado. Serve immediately.

Expert Cooking Tips

• Choose the Right Beef: Using 80/20 or 85/15 ground beef provides enough fat to keep the dish moist and flavorful. If you use leaner beef, you may need to add a tablespoon of olive oil or avocado oil to the pan first.
• Don’t Crowd the Pan: Use a large, 12-inch skillet. This gives the beef and vegetables enough space to brown properly rather than steam, which is key for developing deep flavor.
• Bloom the Spices: Don’t just dump the spices in with the liquids. Tossing them with the beef and vegetables in the hot pan for a minute before adding the tomatoes helps to ‘bloom’ them, waking up their essential oils and intensifying their flavor.
• Drain the Grease (or Don’t): Draining excess grease is a standard step, but if you’re following a strict keto diet, you may want to leave some of that flavorful fat in the pan for extra macros.
• Shred Your Own Cheese: Pre-shredded cheese is often coated with anti-caking agents like potato starch, which can add unnecessary carbs and prevent the cheese from melting as smoothly. For the best gooey, melted texture, buy a block of cheese and shred it yourself.

Substitutions and Variations

This skillet is incredibly versatile. For protein, you can easily substitute ground turkey, ground chicken, or even chorizo; just adjust cooking times accordingly. For a vegetarian version, use a plant-based ground ‘meat’ or a combination of black beans and corn (note: this will increase the carb count). Feel free to swap the bell pepper for other low-carb vegetables like zucchini, mushrooms, or spinach (add spinach at the end, as it wilts quickly). Any good melting cheese works well, so feel free to use all cheddar, Colby Jack, or pepper jack for an extra kick. If you don’t have a can of diced tomatoes with green chiles, use a can of fire-roasted diced tomatoes and add a 4-ounce can of chopped green chiles.

Common Mistakes to Avoid

One of the most common mistakes is overcooking the beef, which can result in a dry, crumbly texture. Brown it until it’s just cooked through, as it will continue to cook with the other ingredients. Another pitfall is not draining enough of the excess fat, which can make the final dish greasy. Be sure to tilt the pan and spoon out the majority of the rendered fat before adding the vegetables. Finally, avoid adding the cheese when the skillet is on high heat. This can cause the cheese to separate and become oily. Lower the heat before sprinkling on the cheese to ensure it melts into a smooth, creamy layer.

Serving Suggestions

To keep this meal strictly low-carb and keto, serve it in crisp lettuce cups (butter or iceberg lettuce work well) for a taco-like experience. It’s also delicious served over a bed of cauliflower rice, zucchini noodles, or a simple side salad. For a hearty bowl, top it with a fried egg. If you are not following a low-carb diet, this skillet is fantastic as a filling for traditional tacos or burritos, or served over a bed of cilantro-lime rice. It also makes an incredible topping for nachos.

Storage and Reheating Tips

Store leftovers in an airtight container in the refrigerator for up to 4 days. The flavors often meld and taste even better the next day. Reheat gently in a skillet over low heat to prevent the cheese from becoming rubbery, or in the microwave in 30-second intervals until warmed through. You can also freeze this dish. Let it cool completely, then transfer it to a freezer-safe container. It can be frozen for up to 3 months. Thaw overnight in the refrigerator before reheating.

Frequently Asked Questions

Can I make this recipe spicier?

Absolutely! To increase the heat, you can add 1/4 to 1/2 teaspoon of cayenne pepper along with the other spices. You can also add a chopped jalapeño or serrano pepper with the onion and bell pepper, or use a hot Mexican cheese blend like habanero jack.

Is this recipe suitable for meal prep?

Yes, this is an excellent meal prep recipe. You can cook the entire skillet ahead of time and portion it into individual containers. It reheats beautifully. For best results, store the toppings separately and add them just before serving.

What if I don’t have all the individual spices?

No problem. You can substitute the chili powder, cumin, paprika, and oregano with 2 to 2.5 tablespoons of a pre-made, low-sugar taco seasoning. Always check the ingredients on packaged seasonings to ensure they are low-carb.
